When you dine-in for Father's Day brunch on Sunday, get a free bottle of maple syrup.

6. BJ's Restaurant and Brewhouse

This restaurant chain is offering a free limited edition pint glass for every day on Saturday and Sunday, Deal News points out via BJ's Facebook page. The company recently introduced an app feature that allows you to order before you dine-in and mobile pay. You also get $5 off $20 when you use "Dine-in Order Ahead" or mobile pay. Oh and June 17, Tuesday, happens to be "Free Pizookie Day," when the restaurant gives away giant cookies with scoops of ice cream.

On Sunday, families can advantage of Hooters' buy 10, get 10 free wings deal exclusive to dads. And if you can't dine-in, get $5 in Dad's Bonus Bucks with the purchase of a $25 gift certificate for dad.

No coupon required. On Sunday, just say "BFD" to get a free burger for the father in your life after the purchase of another burger, as Slickdeals notes.

14. Wendy's

While not giving out freebies to customers, participating Wendy's restaurants will donate 50 cents from the sale of every Frosty product to support the Dave Thomas Foundation for Adoption, which helps find permanent families for the more than 134,000 children in foster care waiting for adoption in North America. The charitable program is part of Wendy's Father's Day Frosty Weekend on Saturday and Sunday.
